Livestock manures have been broadly usedinagriculture sectors forimproving soilproductivity and quality. However, intensive manure applicationscan significantlyenhance soil nitrogen (N) availability, whichmay facilitate ammonia (NH3) volatilization as a major pathway of Nloss during rice cultivation. However, the effectsof different livestock manure applications on NH3volatilization rate, its mechanism,and their relationships have not been investigated well so far. In this study, thefieldtrials were conducted to investigateNH3volatilization by using a static chambermethod with a phosphoglycerol-soaked sponge in rice paddy soilamendedwithdifferentlivestock manures such as cattle manure (CM) and swine manure (SM) at therate of 0 (NPK only as acontrol), 10, 20, and 40 Mg ha-1during cultivation. Moreover, soil physico-chemical andbiological propertiesincluding extractable Ns and ureaseactivity, as well as Nuptake from rice plants were investigated. In addition,ultra-fineparticulate matter (PM2.5) was quantitatively and qualitatively measured by the annular
